Re the cadaver dogs and what was indicated. I always thought it ludicrous to assume that the McCanns hired a vehicle 3 weeks after MM vanished, with the eyes of the world upon them. And then perhaps were involved in an incident that involved a cadaver being placed in the boot. I think there is a possibility of their jobs, the fact they both work in death related scenes etc could be a factor re their clothing. But also, and I'm going to sound like a crazy woman now, but I shall point it out anyway. The lead investigator GA, is leading the team in the possible death of MM, handling of evidence etc. Cadaver and blood dogs involved. Actively working the case - found his pet dog murdered and because he was in a rush to get to work, he put it in the car and discarded of it later! Giving his position, the case itself and the possibility of cross contamination, why on God's earth did he think this was OK? Because make of it what you will, but personally, I thinks it is highly questionable X
